Sorry for the delay in answering your questions, but I just realized that a translation of the new version of my article had been added the forum (thank you Michael !).
To Skyfox:
The concept of bioavailability is explained shortly in part 1.2.2.
In paragraph 4.1 each warning starts with the mention of the toxic element responsible for toxicity of the mineral, however it is also systematically specified "in bioavailable form" only to avoid leaving people under the impression that the mere presence of a given element in a mineral would be sufficient to cause significant toxicity, indeed the said element can only exert significative toxicity when it is in a bioavailable form, which is to say in a chemical form that can actually be absorbed by the body. And as explained in part 2.3.1, in the case of oral route, that would require that the said element would be in the form of a compound that is soluble in digestive juices.
For each mineral listed in part 4.1, you'll find more detailed solubility data and toxicity data (through numerical LD50 values) in part 3.
Of course, the sources for the toxicological data and the solubility data are mentioned in the article (respectively in part 1.2.3 and part 2.3.1)
Concerning the difference in LD values between two animals for the very same compound: part 1.2.3 explains the link between the toxicity class of a compound and its LD50 values, and notably the fact that sensitivity to a given compound may vary between humans and animals, or in other words, between two animal species (as an obvious example, think of the difference between humans and dogs in regard of the theobromine found in chocolate).
Besides, let's note that when the values were established by different research teams, it may occasionally happen that variations in experimental conditions would add to the difference in the obtained values.
To altaj:
Comparing orpiment and realgar (both arsenic III sulfides) would suggest that factors such as its higher solubility in alkaline medium or the possible presence of arsenolite impurities may account for the higher toxicity of orpiment.
To Алексей_3:
Part 1.2.3 explains how LD50 values are used.
Depending on their bioavailability, some compounds of chromium(VI) may indeed classify as highly toxic, just like some arsenic compounds.
To Guru:
You will find detailled handling and storage procedures in part 4.2.
